"t's been two and a half years since Code.org hired our first salaried employee. We've been humbled to watch the landscape change in K-12 computer science (CS) over that time. This teacher-powered movement has reached hundreds of thousands of classrooms and millions of students. We've never been more confident in our ability to realize our vision - that every student in every school should have the opportunity to learn computer science. Although only 25% of U.S. schools teach computer science and computer programming, the field is growing at a rapid pace. Enrollment in computer science is exploding. Over 10% of all U.S. students in grades K-8 registered accounts to begin coding in just the last 2 years. CS is the fastest-growing AP course of this decade. For the first time, the diversity of participating students is improving, with enrollment growth by women and students of color outpacing enrollment growth by White and Asian males."

"This morning TED-Ed released a new lesson that anyone who has ever had a significant surgery may be interested in watching. How Does Anesthesia Work? provides a five minute overview of the history of anesthesia and painkillers used during surgeries. The second half of the video explains the basics of the physiology of how anesthesia works. The lesson is appropriate for high school students taking an anatomy and physiology course."

"My iPad Pro arrived this past week to my excitement. I have used it for just a few days now at this point. There are absolutely no regrets about this large purchase (I joked that it did cost exactly half of what I paid for my first car!). I am thoroughly impressed by this device. The larger size of this iPad gives it a new device feeling, as opposed to just a refreshed model of the same dimensions. For a size reference, here is the iPad Pro side by side with the iPad 4: And here it is next to the iPad Mini:   I hope to do a series of posts outlining my use of the iPad Pro. This first post will just outline some initial thoughts on the device, and who I think it is best suited for. Readers of this blog will know that I'm a huge supporter of using iPads for content creation as opposed to just content consumption. The iPad Pro, along with the new features of iOS 9, bring with it many more possibilities of doing so."

"Over the last year and a half, I been intentionally responding to every complaint I make about education with the following questions: What have I made that helps solve this problem?  If not . . .  Who do I know that is solving this problem? How can I promote that solution?  I don't always have the answers and I don't have the time or the knowledge or the capacity to create solutions. But even that, in itself, is a step in the right direction. Sometimes admitting that you don't know the answer is a part of the solution."

"When Jennifer Lanier began working as a media specialist at Summit Parkway Middle School in South Carolina's Richland School District Two, the school library looked like one most of us remember from our own school days. "There were large heavy tables and chairs with shelves lining all walls," she says.  "It was a very fixed space."  After a period of intensive research, she was ready to make some major changes. "My library is now split into two main sections," Lanier explains, "with the circulation desk as the dividing point.  I focused on renovating the back half first.  This would become the Creative Commons area.  I removed the shelves from the corner, purchased six tall mobile tables, a few stools, six white boards, and twenty beanbag cubes." The idea, Lanier explains, was not to set up the tables, stools and cubes ahead of time but, rather, to leave the furniture out of the way and let users (both students and staff members) grab it and reconfigure the space to meet their needs.  "The arrangement of the space does not dictate the way collaboration is carried out; instead the collaboration can freely flow in the direction it takes.  Users can gather around on the cubes to discuss an idea.  They can break out to a project table and visualize it on a white board.  The simple act of moving allows the brain to be more creative." "

"In 1962, Princeton psychologist Sam Glucksberg performed an experiment based on the classic candle problem test. He presented two groups with the same task, but with different rewards: One would receive monetary rewards based on speed, while the other was told only to complete the task as quickly as possible. The results were counterintuitive. The latter group performed the task on average three and a half times faster than the first. Why? As career analyst Dan Pink (Watch: The puzzle of motivation) has learned, traditional motivators like money can be far less effective than intrinsic motivators like autonomy, mastery and purpose. Indeed, productivity itself is a mystery we still struggle to unravel. Below, find seven must-reads (and a playlist) that look closely at how work works, provided by Pink for his TED Talk."

""More than half of 8-12 year olds are exposed to cyber-risks," according to a 2018 report. These risks can include cyber-bullying, online sexual behaviors and video game addition. The threat is easy to see. Kids today spend hours a day online on computers and phones, much of it unmonitored. To protect your students from online threats you need to raise their Digital IQ. What is Digital IQ? According to the DQ Institute, an international think tank that aims to ensure every child acquires the skills they need to be informed users of digital media, "Digital Intelligence is the sum of technical, mental and social competencies essential to digital life." It's not only skills at coding and working with technology, but also avoiding the risks that technology exposes children to."

"how a fourth grader how to balance a checkbook and it won't be long before her eyes start to glaze over or his mind starts to wander off to more interesting things. Infuse a financial literacy lesson with terms like bitcoin or cryptocurrency, however, and the lesson gets a bit more interesting. Better yet, give the student a very hands-on, tech-centric way to experiment with those financial concepts, and suddenly you're in an entirely new learning realm. As it stands now, a high percentage of K-12 students never getting the tools and training they need to make informed financial decisions. Only a third of states require high school students to take a course in personal finance, while less than half require them to take a course in economics before graduating. So in a push to make learning more relevant-and fun-a pair of startups, BitLearn and Pigzbe, are fusing gamification with finance, propped up by digital currency tokens. Call it the 21st century piggy bank."

"The First Page is a brand new creative writing challenge for students in Grades 7 to 12, created by CBC Books. The challenge? We want students to give us a glimpse of the great Canadian novel of the year 2167. Write the first page of a book set 150 years in the future, with the protagonist facing an issue that's topical today and setting the scene for how it's all playing out in a century and a half."

"t's time to take a look at the micro:bit, which is quite the impressive little device, and see what's packed onto its small surface (4.5 × 5 cm-it's been billed by the BBC as being about half the size of a credit card). I usually introduce new users to a device like this by examining each component one by one, moving clockwise around the board, and that seems like a perfectly reasonable route to take now."

"How much of the internet is fake? Studies generally suggest that, year after year, less than 60 percent of web traffic is human; some years, according to some researchers, a healthy majority of it is bot. For a period of time in 2013, the Times reported this year, a full half of YouTube traffic was "bots masquerading as people," a portion so high that employees feared an inflection point after which YouTube's systems for detecting fraudulent traffic would begin to regard bot traffic as real and human traffic as fake. They called this hypothetical event "the Inversion.""

"I had just pressed the glowing submit button on my screen. After two and a half years, I finally finished my Masters in Computer Science. As the immediate thrill of being done with my coursework subsided, I had a moment of reflection. How had I gone from a high school student who routinely finished in the back of the class to graduating with a near 4.0 in my second graduate program? I went from a bottom of the barrel student to an elite performer with good study habits. Through this story, I would like to highlight the fundamentals that I find instrumental to improving your learning capabilities."

"Stress! It's just a part of everyday life, right? But what if that stress is chronic and beyond a child's control? More than half of all students in U.S. public schools come from low-income families. Poverty is associated with chronic stress, which can have a toxic effect on the brain. While there is no silver bullet to solve the problem of poverty, we as educators do have the power to positively influence learning for children experiencing poverty by better understanding their brains."

"I first became aware that there might be a problem a few years ago, when one of my kids was studying weather systems: high- and low-pressure systems, cold fronts and warm fronts. We were trying to help her prepare for a test and also do some sort of homework, and she didn't get it at all. We were really frustrated, my husband and I, because all we really had as a reference was the top half of this worksheet that explained the concept. So we were having trouble explaining it to her, and at one point I finally said to her, "You know, in your class, didn't your teacher ever draw a diagram on the board?" She said, "No.""

"Like most students at the time, I did not have access to computer science classes when I attended Wilde Lake High School in Columbia during the 1980s. I only stumbled upon the field when my high school math teacher recommended that I take a FORTRAN programming course at Howard Community College. I quickly learned that programming was like nothing I had experienced in school before. Whenever I finally solved a problem, there was a deeply satisfying "aha!" moment. As a result, I studied computer science at Harvard and received my Ph.D. in the field from the University of California, Berkeley. Nearly four decades after I took that first FORTRAN class, I'm a professor of computer science and associate dean at the University of Maryland, Baltimore County. I was fortunate to have found my passion, even though computer science was not taught at my school. The unfortunate fact is that most K-12 schools still do not teach computer science, and most of today's high school and college students - particularly women - have still had little or no exposure to computational thinking, coding or computer science. There are certainly many students who would make great computer scientists, or who could leverage computing skills to achieve success in any number of other fields, who never take a single related class. Even in Maryland, one of the most technologically advanced states in the nation, only 14 percent of students take a computer science class in high school, and nearly half of the public high schools do not offer any AP computer science classes."

"Data is on overdrive. It's being generated at break-neck pace, flooding out of the dozens of connected devices we use every day, and it shows no signs of slowing down. In fact, the number of internet users has grown over a billion in the last five years, more than half of the world's web traffic now comes from mobile phones. In its fifth year, Data Never Sleeps shows exactly how much data is created every single minute. From tweets to swipes, likes to shares, the digital world is exploding. Have a look."

"This is my third summer offering maker education summer camps as part of a bigger program at a local school.  During mornings (9 to 12 with a half hour recess), campers, grades Kindergarten through 6th grade, can choose from one of four enrichment classes: art, drama, games, foreign languages, computers, and in my case, maker camps. During the afternoons, all campers get together for typical camp activities - fun and games, field trips, water sports, silly competitions. Each camp lasts a week. This summer I am offering: Cardboard Creations, Circuit Crafts, Toy Making and Hacking, and Robotics and Coding. I often discuss the need to implement maker education programs with minimal cost materials and ones that offer the potential to tap into diverse learners and their diverse interests:"

"Summer fun. It is the absolute best. Whether you visit Six Flags, Kings Island, a Disney Park, Busch Gardens, or another amusement park, the looping lines of roller coasters offer the perfect lens for getting students to interact with STEM concepts. An old garden hose, duct tape, and a marble: the only materials that you need to build a roller coaster. Cut the hose in half, and then duct tape the two segments together down the back to create a nice groove where the two hoses meet for the marble to ride, on top. Then the materials are ready for students to explore the potential and kinetic energy of roller coasters."

"For the most part, American children aren't great at math. But Chinese children tend to be excellent. Testing half a million students worldwide, the Program for International Student Assessment is one of the most widely cited measurements of global education, and it's consistently found Chinese students at the top of the academic pile ... and Americans much nearer the bottom. Some experts argue that the PISA assessment, like any standardized tests, primarily measures a student's ability to take the test, not their knowledge, but hardly anyone disputes that the American education has some work to do when it comes to math.  In Lenora Chu's new book "Little Soldiers: An American Boy, a Chinese School, and the Global Race to Achieve," she begins to unearth the cultural differences that lead to this gap - and it's not just about what happens at school."
